Dear Forum,
In recent weeks, I shared my experiences searching for and selecting a construction company. Thanks again for all your help and discussions!
As promised, I am posting our current plans here and would appreciate your comments and suggestions. Some minor details are not ideal but likely cannot be changed – I have explained these below.
Development Plan / Restrictions
Plot size: 340m² (3,659 sq ft)
Slope: Yes, approximately 2m (6.5 ft) difference over 17m (56 ft) length
Site coverage ratio: 0.4
Floor area ratio: none
Building envelope, building line and boundary:
Maximum building envelope for semi-detached house: 8x13m (26x43 ft)
Maximum garage building envelope: 5x9m (16x30 ft)
Building boundaries may be exceeded by a maximum of 5m (16 ft) in width and 1.5m (5 ft) in depth per building side, as well as by minor structural elements
Number of parking spaces: 2 cars and 2 bicycles
Storeys: No direct specification, but height limits above sea level apply
Roof type: Gable roof, 30-40° pitch
Architectural style: -
Orientation: Southeast
Maximum heights/limits:
Maximum eaves and ridge heights are given as heights above sea level.
No roof structures are permitted on the north side.
Additional requirements:
A cistern is mandatory. The maximum height of the garage within its designated envelope is specified.
Client Requirements
Style, roof type, building type: Modern, gable roof, semi-detached house
Basement, floors: At least two floors required; the open basement results from the slope
Number of occupants, age: 2 adults in their early/mid-30s, planning for 1-2 children
Space requirements on ground and upper floors:
Ground floor: office, living room, dining room, kitchen, pantry, and shower/WC
Upper floor: bedroom, dressing room, bathroom, and two children’s bedrooms
Office: family use or home office? An office is essential
Overnight guests per year: 2-3 times
Open or closed architecture: Good mix. Kitchen, dining, and living areas are mostly open; the rest are mostly closed
Conservative or modern construction: Modern construction preferred
Open kitchen, island: Open kitchen with island
Number of dining seats: 4-6
Fireplace: Yes, if feasible
Music/sound wall: ?
Balcony, roof terrace: No, not needed
Garage, carport: Double garage is not possible due to development plan restrictions. Therefore, a slightly wider single garage with space for trash bins and bicycles.
Utility garden, greenhouse: No
Additional wishes/special features/daily routine, reasons for preferences:
The master bedroom can be smaller since it is only for sleeping; the space should benefit other rooms.
A large bathroom with a spacious, airy feel.

House Design
Planning source: Discussions with the general contractor and implementation by architects
What do you especially like? Why?
Bathroom – relatively large, wide double vanity, WC somewhat hidden, and walk-in shower without enclosure
Staircase – not too tightly curved for a semi-detached house
Children’s rooms – equally sized but not mirrored exactly, slightly different layouts
What do you not like? Why?
Pantry – unfortunately not directly behind the kitchen, with stairs in between
Ground floor WC – initially planned as a shower toilet but moved to basement due to space constraints
Estimated cost according to architect/planner: approx. 2,400 euros per m² (approx. $220 per sq ft)
Personal price limit for house including fittings:
Preferred heating system: Air-to-water heat pump as a split unit – suggested model was "Weishaupt Air/Water Heat Pump Biblock (WWP LB)"
If you had to give up, which details or expansions would you skip
-Could you skip: Fireplace, granny flat, size of basement hallway, knee wall in master bedroom
-Cannot skip: Large bathroom, pantry and ground floor WC, office
Why was the design created this way?
We discussed our wishes for each floor with the general contractor, who then worked with the architect to create a design.
We reviewed and adjusted the design several times to meet our needs.
The suggestion to place the kitchen directly by the terrace and the living room more inward came from the general contractor.
Additional remarks:
We acquired a plot for a semi-detached house and after long research chose a solid construction provider.
Besides standard rooms, we require two children’s rooms and a home office. Due to the slope, a three-story building with an open basement at the front evolved. An open kitchen-dining-living area with a possible small division to the living room via a fireplace is important to us.
The general contractor proposed placing the kitchen on the garden side for easy access between garden and kitchen/refrigerator, especially in summer. The living area was placed more inward for more privacy. Initially, this seemed unusual since most floor plans are the other way around. Now we find it quite interesting.
After the first draft, two problems arose: the kitchen was too narrow for our ideas. We wanted an open kitchen with a large central island. The dressing room upstairs was hard to use due to layout and a 2m (6.5 ft) boundary line. We reworked the plan extensively and had to move the staircase, which affected the layout on all floors. The dressing room has become acceptable and usable. Unfortunately, these changes meant that the pantry was no longer behind the kitchen and the ground floor WC lost its shower. We see no option to change this without causing other issues.
We do not actually need a granny flat. However, due to the open basement design, an extra room emerged. Initially planned as a hobby room, it became a granny flat because the ground floor shower had to be removed and we wanted a second shower for safety. This is not bad for several reasons: 1) if we are older, we would have everything needed downstairs and on the ground floor; 2) if a child wants to move in, they have a WC and shower; 3) there would be a second shower in the house (in case there are three women living here).
And if you wonder why the house is so large with 192m² (2,067 sq ft) of living space:
We never planned for so much space; it developed naturally. We do not want to change the width of 8m (26 ft), as it would become too narrow. The length of 12m (39 ft) could theoretically be reduced, but currently, only the basement area seems oversized. On the ground floor, space is tight for pantry and shower, and upstairs for dressing room layout.
That’s the overview of our ideas and plans. I look forward to your comments and questions.
What is the most important/basic question about the floor plan in 130 characters?
We would appreciate general opinions on the floor plan.
Have we overlooked anything that only becomes apparent in daily life?
Are there smarter ideas for alternative layouts?
What do you think about the kitchen’s layout and size?
What about the garage size? I’m unsure whether width or length is more important.
What do you think about the door orientations? Some open inward, some outward due to space. Is this inconvenient or acceptable?
If anything is missing, please let me know.
PS: The exterior design of the house and garage (color, wood between windows, etc.) and the type of doors in the dining room (sliding/door/fixed) are not finalized and just roughly sketched. Please disregard.
Thank you!
//Edit: If anyone wonders why the maximum roof height in the plan differs slightly from the building roof height: this was a later change to the development plan and is correct.

We have a slightly sloping plot and were not allowed to set the garage back from the boundary because that would have created a so-called "dead strip" between the garage and the neighbor’s property—a narrow strip that is difficult to maintain. So the garage had to be either right on the boundary or far enough away. This probably doesn’t apply to your situation, since the strip is wide enough for you to maintain it. A wider but shorter garage would be more practical for me, as I wouldn’t have to carry or move everything around the car; instead, I could store items right next to it. Otherwise, you’re effectively losing usable space that apart from the outdoor unit you can’t really use. No one would do this here in Munich, but considering that you need to shield the street, your solution is probably the smarter one.
Two comments:
Why place the living room on the street side and the stairs to the garden there? I would plan it the other way around.
I don’t find the bedroom with the walk-in closet very practical, and since it’s only supposed to be used for sleeping and can be smaller, in my opinion it has become quite large.

Two notes: Why is the living room on the street side and the stairs leading to the garden? I would have planned it the other way around. I don’t find the bedroom with the walk-in closet optimal, and since it is only supposed to be used for sleeping and allowed to be smaller, in my opinion it has become quite large. I assume you meant the kitchen instead of the stairs? The layout was created by our general contractor / planner, and at first, we also found it a bit unusual. Especially because it feels like 90% of floor plans have the living room facing the garden. Over time, though, we actually like it this way, as it provides a short route to the kitchen and refrigerator in the summer. And especially when guests are over, that path is used more often than the living room. The street on the left side (west) is just a dead-end road leading to two other buildings (see the first plan in the first post).
I agree with you about the bedroom. We originally wanted just a small bedroom and to have the other rooms larger, but somehow it ended up like this. There is currently about 1.2m (4 feet) of clearance between the bed and the wall, so it might be possible to reduce that a bit and allocate that space to the bathroom. Does that make sense?
Latest changes (plan to follow):
- Child 2 – door opens inward
- Child 1 – wall slightly moved toward the hall/foyer
- Kitchen/Dining – the two large windows replaced by a 5m (16 feet) long lift-and-slide door

erazorlll14 Jun 2020 22:27One more question for the group:
We are still considering whether to have an open ridge in the attic (so basically without a ceiling) or a standard ceiling height. The general contractor said an open ridge would look quite good in the rooms, but I’m still totally unsure.
Does it really look good when the ceiling rises only slightly at the wall and then goes very high? In the outer rooms (bedroom, kids’ rooms 1 and 2), that would be between 3.00–3.30 meters (9.8–10.8 feet), and in the bathroom, the ceiling would be 4.30 meters (14.1 feet) high. I also imagine it could be difficult with lighting and so on—especially if you want to install spotlights in, for example, the shower.
In the hallway, we definitely want to do it because of the roof window. But in the other rooms, I’m not really sure.
I’d be interested in your opinions, and what you see as the advantages and disadvantages.
